Bugfix: advertise a license

 * BSD-2-Clause ;)
 * bump up version to 0.1.1

cc @bf4
Enhancement: at LICENSE.txt

cc @fh - next time, let's use bundler
Fix: always run `bundle install`

 * git rm Gemfile.lock
 * bundle install --no-deployment
 * git add -A .
Update: remove .lock per suggestion from The Josh
